Document keywords

Although the database is fully searchable we have tagged some keywords in
every document, and these are listed via this page.

This process of tagging will be expanded and refined in a subsequent
phase. In particular, further work is required on a list of synonyms, and
especially on a forward convention on naming protocols in the keyword
lists. This will be developed with reference to the example of
The Years of the Cupola and ongoing
discussions with the Medici Archive Project.
